IMPROVEMENT IN WATER-WHEEL.

4 Be it known that we, GEORGE W. CnEssMAN and BERT PFLEGER, of'BarrenHilI, in the county ot' Montgomery, and State otPennsylvania, and NICE KEELY, of 'the' city of Roxborough, in the county of Philadelphia, `and State of Pennsylvania, have invented a new and useful Improvement in 'Water- .Wheels; and we do hereby declarethat the followy ing is a full, clearfand exact description thereof,

which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

t 'lliisinvention relates to improvements in turbine- `wheels, designed to provide an arrangement of lthe gates within the bucket-lim, (the water being received from below andthe wheel being made hollow, for theV reception of thewater, and to provide space for the said gates,) kin a manner .calculated to relieve the wheel of pressure from the water, either in an upward .orl downward direction, all as hereinafter more fully specified. f

Figure l represents aplan' -view, :partly broken, of uur improved wheel.

Figure 2 represents asectional elevation of the same, taken on the line x-x of tig. 1.

Similar letters of-reference indicate corresponding parts'. i

We arrange the case A of the wheel with a large opening, B, at the bottom, for the reception of the water to the liorizontally-revolving wheel C, having `buckets of. ordinary construction.

`We suspend'thcnbucket-rims C from the disk C, in a manner to hollow out the wheel within the `bucketrilns for the reception ot the gates D,land the disk E A above them, and'on which they are supported at their upper ends in journals E', the lower journals being pivoted in the elevated rim F of the lower part of the case. f In theitop of the lower part of lthe case we make actuating the buckets.

' The periphery ofthis ring is located justwithin the lower journals of the gates, and the upper face is provided with studs H, rising up' one on each side 'off each bucket, so that the rotation of the ring will open and close the gates by swinging them in either direction on their journals. y

The said gates are preferably made ill the formof a crescent, whereby the pointsI on which the water is received have a radial, or nearly radial direction, from which their concaved surfaces, when 'in the open condition, gradually changethe'l course of the water to` give the most direct impact against the concave faces of the buckets, as clearly shown in iig. 1. ,n

Folzoperating the rim (-19,3. lportion of its under surface isV toothed, and a toothed segment, I, is supported in a recess in the case, out of the way ot' the intlowingvolume of water, on a short shaft passing through the case in a stuliing-box, und provided with a handwheel on the outside.v

It will be observed that by this'arrangement the wheel is not exposed to vert-ical pressure from the water ineitherdirection, iieitlieimvlien standing nor running.

Having thus described our invention,

That we claim as new, and desire to secure by Letters Patent, is

1. The hollow whe-el, wheel-case, gates, disk E, and ring G, all combined and arranged substantially as specified.

2. The gates D, ring G, pins H, toothed 'segment I, and hand-wheel and shaft, all arranged as specified. GEORGE \V. CRESSMAN.'
